Referring to FIGS. 1 and 2, a connection member 10 is schematically illustrated. In various embodiments, the connection member 10 is a generally tubular, hollow member having a longitudinal axis A. The connection member 10 is used to couple multiple components, such as vehicle body components in a vehicle body assembly. The connection member 10 has a first end 22 and a second end 24 opposite the first end 22. The connection member 10 also has a top 26 and an underside or bottom 28. The connection member 10 includes a first side 12, a second side 14 opposite and approximately parallel to the first side, and a third side 13 adjacent to each of the first and

second sides

12, 14 and connecting the first and

second sides

12, 14. A fourth side 11 extends the length of the connection member 10 from the first end 22 to the second end 24 and is adjacent to and connects the first and

second sides

12, 14. The fourth side 11 is separated from the third side 13 by the first and

second sides

12, 14. In various embodiments, the fourth side 11 includes one or more cutouts or connection points to couple the connection member 10 to a vehicle chassis component, for example and without limitation.

The first, second, third, and

fourth sides

12, 14, 13, 11 define an interior space 21 of the connection member 10. In various embodiments, a support member 18 extends through at least a portion of the interior space 21. The support member 18 is adjacent to and connects the first and

second sides

12, 14, as best shown in FIG. 1. In various embodiments, the support member 18 is approximately parallel to the fourth side 11. The support member 18 provides rigidity and support to the connection member 10. In various embodiments, the support member 18 extends along a lateral axis B of the connection member 10 such that the lateral axis B passes through each of the first and

second sides

12, 14.

In various embodiments, the third side 13 includes a plurality of adjacent surfaces connected by edge members. Each of the plurality of adjacent surfaces defines a plane and each plane is oriented at a different angle (that is, each plane is non-coplanar) depending on the intended connection between the connection member 10 and the coupled component. As shown in FIG. 2, the third side 13 includes a first portion 23 defining a first plane, a second portion 25 defining a second plane, and a third portion 27 defining a third plane. The first, second, and third planes are non-coplanar. A first edge 15 separates the first portion 23 from the second portion 25 and a second edge 17 separates the second portion 25 from the third portion 27. A plurality of flanges extends from each of the first and second edges 15, 17 to enable connection of multiple components using the connection member 10.

In the exemplary embodiment shown in FIGS. 1 and 2, a first flange 32 extends from the first edge 15 at the first end 22 of the connection member 10. A second flange 34 also extends from the first edge 15 at the second end 24 of the connection member 10. A third flange 36 extends from the second edge 17 of the connection member 10. The first, second, and

third flanges

32, 34, 36 are arranged to allow connection with multiple other components. In various embodiments, one or more portions of one or more of the flanges may be cut away or removed where not needed for coupling to other components. The third flange 36 includes a first portion 37 and a second portion 38 defining a gap 39. The first, second, and

third flanges

32, 34, 36 extend longitudinally along the connection member 10 parallel to the longitudinal axis A.

In various embodiments, including the embodiment shown in FIGS. 1 and 2, the first portion 23 slopes away from the first flange 32 at a first angle and the third portion 27 slopes away from the third flange 36 at a second angle. The angle of slope of the first portion 23 may be the same as or different from the angle of slope of the third portion 27. The angle of slope of each of the first and

third portions

23, 27 is determined based on the intended components to be coupled using the connection member 10 such that the shape of the connection member 10 does not impede the connection between the intended components and the one or more of the flanges of the connection member 10.

In various embodiments, the connection member 10 is extruded with multiple flanges that run the length of the connection member 10, that is, a first flange extends along at least a portion of the length of the connection member 10 and a second flange extends along at least a portion of the length of the connection member 10. In various embodiments, the first flange extends along the first edge 15 and the second flange extends along the second edge 17. The flanges can be machined or cut away to the desired configuration based on the intended components to be coupled together. Thus, the connection member 10 with multiple flanges can be customized through machining to obtain the desired configuration, length, and number of flanges.

As best shown in FIG. 1, the

flanges

32, 34 do not extend the full length of the connection member 10. Furthermore, in some embodiments, the

flanges

32, 34, 36 do not overlap, that is, the flanges extending along one edge do not overlap with flanges on the other edge. However, in other configurations, one or more flanges along one edge may overlap with one or more flanges along the other edge. In various embodiments, the one or more flanges extending from the first edge 15 are “inner” flanges configured to mate with components arranged inward of the connection member 10. In various embodiments, the one or more flanges extending from the second edge 17 are “outer” flanges configured to mate with outboard components including structural components such as a B-pillar of a vehicle body assembly. However, it should be understood that the terms “inner” and “outer” are used to generally indicate a direction and the connection member 10 may be manufactured with any number of and position of flanges to facilitate the mating of one or more components.

FIG. 3 schematically illustrates the connection member 10 coupling together two components 52 and 54 in an exemplary method of coupling vehicle components. In various embodiments, the components 52, 54 are vehicle body components. The position and length of each flange of the connection member 10 can be customized depending on the intended configuration of the coupled components. As shown in FIG. 3, the tubular connection member 10 defines a longitudinal axis and has a first side, a second side opposite the first side, a third side connecting the first and second sides, and a fourth side connecting the first and second sides. The third side includes a first portion defining a first plane, a second portion defining a second plane, and a third portion defining a third plane. The third side also includes a first edge and a second edge, the first edge separating the first plane from the second plane and the second edge separating the second plane from the third plane. The first vehicle body component 52 is coupled to the first flange and the second vehicle body component 54 is coupled to the second flange such that the first and second vehicle body components are laterally spaced from each other.

While FIG. 3 illustrates two components coupled to the connection member 10, it is understood that three, four, or more components may be coupled to the first, second, third, or more flanges of the connection member 10, depending on the length and position of the flanges.

While FIGS. 1-3 illustrate a connection member 10 having a three-flange configuration, it is understood that other embodiments may include more or fewer flanges arranged on the connection member 10 to accommodate and couple a multitude of components.

In various embodiments, the connection member 10, including each of the flanges, is formed as an extrusion. The flanges can be machined or otherwise cutaway to produce the desired length and configuration of flange(s). In various embodiments, the connection member 10 may also be formed via any other manufacturing method such as casting, 3D printing, welding, etc. as known to those skilled in the art.

It should be emphasized that many variations and modifications may be made to the herein-described embodiments, the elements of which are to be understood as being among other acceptable examples. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims. Moreover, any of the steps described herein can be performed simultaneously or in an order different from the steps as ordered herein. Moreover, as should be apparent, the features and attributes of the specific embodiments disclosed herein may be combined in different ways to form additional embodiments, all of which fall within the scope of the present disclosure.

Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or states. Thus, such conditional language is not generally intended to imply that features, elements and/or states are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or states are included or are to be performed in any particular embodiment.

Moreover, the following terminology may have been used herein. The singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an item includes reference to one or more items. The term “ones” refers to one, two or more, and generally applies to the selection of some or all of a quantity. The term “plurality” refers to two or more of an item. The term “about” or “approximately” means that quantities, dimensions, sizes, formulations, parameters, shapes and other characteristics need not be exact, but may be approximated and/or larger or smaller, as desired, reflecting acceptable tolerances, conversion factors, rounding off, measurement error and the like and other factors known to those of skill in the art. The term “substantially” means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.

While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms encompassed by the claims. The words used in the specification are words of description rather than limitation, and it is understood that various changes can be made without departing from the spirit and scope of the disclosure. As previously described, the features of various embodiments can be combined to form further exemplary aspects of the present disclosure that may not be explicitly described or illustrated. While various embodiments could have been described as providing advantages or being preferred over other embodiments or prior art implementations with respect to one or more desired characteristics, those of ordinary skill in the art recognize that one or more features or characteristics can be compromised to achieve desired overall system attributes, which depend on the specific application and implementation. These attributes can include, but are not limited to cost, strength, durability, life cycle cost, marketability, appearance, packaging, size, serviceability, weight, manufacturability, ease of assembly, etc. As such, embodiments described as less desirable than other embodiments or prior art implementations with respect to one or more characteristics are not outside the scope of the disclosure and can be desirable for particular applications.
